To all toil 0-121 it may concern lie it known that I, Illt'NlttY :llt'lltlil ltt'l. Ynrir, a subject ol the iliiug of Great Britain, rcsiding' at nil lelhatn road, tz outhsea, lortsmouth, in the county of l'l anlpshire, England, have invented certain new and useful Inun-orcinents in tililencing and Anticoiwussive Supports t'or Type-Writing Machines and the like, of which the following is a specification.

This invention relates to improvements in silencing and aiiti-concussive supports for typewriting machines and the like, and has for its object to provide improved simple and cheap devices of the kind applicable to the feet of typewriting uiachines and other machines in which noise is produced by the striking, of keys or similar manipulations, whichdevices ell'ectually deaden the sound and absorb the shock produced in working and thereby render the operation as silent as possible.

A further. object of the invention is to provide supports of the character indicated in which the supports grip and are left attached to the test of the typewriting machine when the latter is lifted about or is placed in or beneath its casing or cover.

According to this invention a pad which is readily attachable and detachable is vided for each foot of the typewriting; machine and consists of a disk prelferablycin cular of felt, iniliaruhber or like anti-c011- cussive and non-resonant material, with a cover plate of metal, wood, celluloid, or other rigid material capable of distributing over the area of the anti-concussive disk the pressure of the foot due to the weight of the machine and the operationthereof Upon the disk a clip such as a circular clip or circular series of grippers is provided for enabling the pad to be attached to the foot oi the machine all as will be hereinat'ter partirularly described and ascertained by reference to the accompanying drawings in which Figure 1 is a side elevation ofoue form of anti-concussive support or pad constructed in accordance with these improvements. Fig. 2 is a plan of Fig. 1. Fig.1) 1s a central vertical section of the pad seen. in Figs. 1 and 2 secured to the. foot of a typowriting machine or the trite, the root being shown in elevation and a portion of the base plate ot the now chine being SllOWIll'lIl section. Fig. 4 1s a pro detail .ierspe 'tive view of the clip or gripper seen in Figs. 2 and 3. Figs. 5 and (5 are perspective views of anti-concussive supports or pads titled with modified lorius ol. clips or grippers.

In the various figures of the rlrnwingsa is the pad or support of anti-concussive or shock absorbing material and consists of a circular disk ol 'l'ult, india-rubher or other suitable material and is the cover plate of metal, wood, celluloid, or other rigid material *apable of distributing over the anticoncussive disk the pressure of the foot of the machine and to the operation isv fixed a clip, spring grippers 0 Figs. 1 to l adapted to clip on to the tool, a! of the base plate a of a machine as shown in Fig. The plate 6 is secured to the pad a by cementing or gluing thereoh Upon the disk or by punching or beniling down small ears or clips (not shown) at the periphery of the plate so as to clip the felt, or both adhesive and clips may he used, and the grip ans '0 are secured to the plate, as shown in igs. 2 and 4;, by pass'sing a rivet through such plate and through crosset blade spring; members g, the end portions of which are bent upward so as to stand about vertically and form the circular series of grippers c. The free ends are bent dmvnwardaand inr wurdly, as clearly seen in Figs. 3 and t, so that the free ends it provide yielding SUI" 'lacesfor gripping the end of a foot (I which is forced in between such yielding or spring portions it.

As shown in Fig.5,the clip is formed of a ring composed of zig-zag or waved wire j some of the lower bends ls oi which are pinned, or riveted, as at Z, or otherwise suit-- ahly fastened to the upper surface of the cover plate 7), leaving the circular series of upper bends 't'rceafor engaging with and gripping the foot of the typewriting niachine. The clip seen in Fig. 5 thus I'EStllb bles a spring wire basket into which the existing or usual chine is pressed.

As shown in Fig. 6, tllUfOOt of the machino.is gripped by a clip consisting of two parallel pieces or strips mi of waved or zignag wire which are fixed to the plate (I by rivets a in a manner similar to that doscribed with reference to his. 33. in rd r to be engaged With a circular fool'- the strips due to the weight of the latter such as a circular series of foot of the typowriting ma m W011i (1 be bent outwardly away from one s'hether to allow at the insertion of the feet but they Height of cemse, be engaged. with other shape of feet such. to): exam- 1 (W21, oblong 01- squere foot.
